Embodiment Construction

[0018] The invention provides an air supply and exhaust welding fume purification device, which improves the filtering wind speed, is suitable for filtering and purifying large-scale workshops, and has a high degree of automation. The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0019] Such as figure 1 As shown, the air supply and exhaust welding fume purification equipment provided by the present invention includes an exhaust fan unit, a blower unit and a PLC control system. The exhaust fan unit is used to purify the exhaust gas in the workshop, and the air supply unit is used to purify the outdoor air and introduce it into the workshop. When the two cooperate to operate, they are used to further purify the exhaust gas.

[0020] The two sides of the exhaust fan unit are respectively provided with an air inlet 1 and a first ventilator, along the direction of the air flow, a first filter layer and a f...

Abstract

The invention discloses a blowing-exhausting welding-fume purifying device. The blowing-exhausting welding-fume purifying device comprises an exhausting unit, a blowing unit and a PLC control system. An air inlet and a first ventilation opening are formed in the two sides of the exhausting unit respectively, a first filter layer composed of a plurality of efficient film covering filter drums and a first draught fan are sequentially arranged in the direction of airflow, and an indoor air supplementing opening is formed in the back side of the first draught fan. A second ventilation opening and an exhausting opening are formed in the two sides of the blowing unit respectively, a primary filter, a medium-efficiency filter and a second draught fan are sequentially arranged in the direction of the airflow, the second ventilation opening is communicated with the first ventilation opening, and an outdoor air supplementing opening is formed in the front side of the primary filter. The PLC control system comprises a signal receiver and a PLC, and is electrically connected with the first draught fan and the second draught fan. According to the blowing-exhausting welding-fume purifying device, waste gas in a workshop is purified through the exhausting unit, outdoor air and indoor air can be purified through the blowing unit, a dual-air-inlet mode can be adopted, the filtering air speed is increased, and the blowing-exhausting welding-fume purifying device is suitable for filtering and purifying of a large workshop and is high in automation degree.

Description

technical field [0001] The invention relates to welding fume purification equipment, in particular to air supply and exhaust welding fume purification equipment. Background technique [0002] The organic waste gas produced by petrochemical, pharmaceutical, printing, painting, shoemaking, decentralized welding, automatic welding, CO2 gas shielded welding, argon arc welding, DC welding and other industries is very harmful to human health: it is harmful to human eyes, The nose and respiratory tract are irritating, harmful to the heart, lungs, liver and other internal organs and the nervous system, and even cause acute and chronic poisoning, and can cause cancer and mutagenesis. [0003] Existing smoke and dust control equipment mainly includes: filter cartridge dust collector, bag filter, oil fume purifier, etc. The above-mentioned equipment generally has a single processing function, and can only deal with the purification system of welding workshops with small air volumes, an...
